A Study on the Analysis and Design of IT Cost Model Using an Ethnographic Research

Ethnographic Research를 이용한 IT Cost 모델 분석 및 설계

The purpose of this study is to provide and validate an IT cost model hi which we link among cost center, cost object and flexible cost driver. in order to accomplish this purpose, this study utilizes ethnographic research methodology. At first we develop the cost model where the flexible cost driver is the distribution basis of overhead cost. For each cost driver, unit cost management model is also proposed. Then we employ the structured design methodology to validate the model. Based on the IT Cost requirements of a case company, the IT cost system was designed and developed for its test. The result shows the model we developed in this study is appropriate for managing IT resources and further, can be used as a reference model for calculating chargeback rates of other departments and IT budget of IT department.
